Social media strategy and delivery (Spanish language)

I am looking to develop a comprehensive Spanish-language social media strategy and delivery for our organization. The main target will be Instagram, Facebook, etc.. We have our content to be used. we are looking for an ongoing engagement with the right individual or team that can help to create a comprehensive strategy tailored to our organization's requirements and execute it, with ongoing results. If you have the skills to do this and speak Spanish fluently, I would love to hear from you. We are a non-profit organization that promotes clean mobility to Hispanic consumers in the USA. We want to start fresh with a clean sheet of paper. Gives us your best proposal, on how to develop at least 100k followers from scratch. We have been approached by several people but we have not seen an action plan backed by proven results. Show us what you have done for consideration. This is an ongoing project.
